Two Hatchbacks, but completely different in all significant aspects: model year, starting price, fuel economy, market segment, ground shadow size, height, and maximum occupancy. First of all, there is a $12,240 difference in the base MSRP. The 2013 FIAT 500e, an older vehicle by three model years, has a higher starting price than the 2016 Toyota Prius c. Also, the 2016 Prius c gets 66 more miles on a gallon than the 2013 500e. In addition, comparing the dimensions we see that the 500e is slightly smaller, although it's taller than the Prius c. And then, you'll seat one more passenger in the Toyota Prius c than in the FIAT 500e. Among similarities is the body structure.
